The default tuning came up in the context of bsf vs. tzcnt here:
D117912 <https://reviews.llvm.org/D117912>
So I wasn't expecting a bump in default tuning yet, but I think it's great.

But I agree that this change may cause a lot of surprises, so users need to be given notice (add a line to the clang release notes?) and wait for the 14.0 branch to be created.

Should we have a test file that intentionally shows codegen changes as this setting gets updated?
